Re: [mpls] MPLS Working Group Last Call on draft-ietf-mpls-mna-requirements

[Gyan Mishra <[e-mail]>]

Hi Loa

I have reviewed the latest version of the draft and the draft is well
written and I agree that both ISD and PSD should be included in the
requirements draft.

As far as publication I don’t see any harm in publication as it has a lot
of good information history on requirements as the solution space develops.

I agree with the comments made my Adrian on the formatting and nits.

Just a comment of existing solution and existence and examples of ISD and
PSD that exist today.  So RFC 6790 Entropy label and RFC 8662 SR-MPLS
Entropy label are good examples of ISD.

RFC 8660 SR-MPLS over v4 or v6 data plane would be examples of ISD that
exists today.  SR-MPLS extends the traditional label stack RFC 3032 label
stack encoding to support stacking of topological labels at the transport
layer along with ELI,EL encoding great example of ISD.

For the 2 use case groupings HBH and E2E we have a few existing data
solutions for HBH using ISD above, but I can’t think of any that use PSD
for E2E, however I think keeping E2E in scope as drafts solutions are
progressed makes the extensibility of the architecture flexible for
designers in the future.  I think PSD is forward looking and should be kept
in scope as solutions are developed.

Thank you

Gyan
